Mapping of modm

[brinzebuah]

Hey guys, can you tell me how you did the mapping of the nucleoF439zi?
I want to generate some Code, therefore i made a map from the nucleoF439zi manual with all GPIO, Timer- and ADC-Functions. My code checks this map and use unused Pins in my main.cpp. But i got 2 Issues during testing:

1. Why can't i use Timer 9? (Error: 'Timer9' is not a member of 'Board::SystemClock')
2. When i want to use ChXn Channel to get a 50/50 PWM signal, I get this errors:

modm/src/modm/platform/timer/general_purpose_base.hpp: In instantiation of \
    'static consteval int modm::platform::GeneralPurposeTimer::signalToChannel() \
    [with modm::platform::Peripheral p = modm::platform::Peripheral::Tim8; Signal = modm::platform::detail::DataB1::Ch3n]':
modm/src/modm/platform/timer/timer_8.hpp:373:69:   required from \
    'static void modm::platform::Timer8::configureOutputChannel( \
        modm::platform::GeneralPurposeTimer::OutputCompareMode, Value, \
        modm::platform::GeneralPurposeTimer::PinState) [with Signal = modm::platform::detail::DataB1::Ch3n; Value = short unsigned int]'
modm/src/modm/platform/timer/general_purpose_base.hpp:274:40: error: static assertion failed: Invalid timer channel
  274 |                         static_assert(!sizeof(Signal), "Invalid timer channel");

I also don't really understand the differnece between the CN7-CN10 and CN11/12 connectors. Has a GPIO on both connectors the same functions, or is there some internal wiring, which limits the functions of the GPIO.
I hope you can help me a bit.

how you did the mapping of the nucleoF439zi?

Manually, by copying the relevant data out of the User Manuals.
Unfortunately there's no machine-readable dataset available for pinout mapping of their boards, only the PDFs. I'm (slowly) working on modm-data to parse such information out of the PDFs (see also) .

Why can't i use Timer 9?

It was just forgotten during the BSP creation. Please add it in a PR.

When i want to use ChXn Channel to get a 50/50 PWM signal, I get this errors:

The function here contains the generated list of signals that can be connected to. Seems to be correctly generated, should return 3.

	template<Peripheral p, typename Signal>
	static consteval int
	signalToChannel()
	{
		modm::platform::detail::SignalConnection<Signal, p>{};
		if constexpr (Signal::Signal == Gpio::Signal::Ch1) {
			return 1;
		} else if constexpr (Signal::Signal == Gpio::Signal::Ch1n) {
			return 1;
		} else if constexpr (Signal::Signal == Gpio::Signal::Ch2) {
			return 2;
		} else if constexpr (Signal::Signal == Gpio::Signal::Ch2n) {
			return 2;
		} else if constexpr (Signal::Signal == Gpio::Signal::Ch3) {
			return 3;
		} else if constexpr (Signal::Signal == Gpio::Signal::Ch3n) {
			return 3;
		} else if constexpr (Signal::Signal == Gpio::Signal::Ch4) {
			return 4;
		} else {
			// assert is always false, static_assert(false) would not compile
			static_assert(!sizeof(Signal), "Invalid timer channel");
		}
	}

The generated GPIO data also looks fine:

struct DataB1 {
	static constexpr Gpio::Port port = Gpio::Port::B;
	static constexpr uint8_t pin = 1;
	struct Ch3n { using Data = DataB1; static constexpr Gpio::Signal Signal = Gpio::Signal::Ch3n; };};

Not sure what's broken.
You can use the manual method as a workaround:

configureOutputChannel(uint32_t channel, OutputCompareMode mode, Value compareValue, PinState out = PinState::Enable);

Has a GPIO on both connectors the same functions

Yes, the GPIOs are shared between both connector types.
